Abstract

This paper presents the ultra-wideband (UWB) channel measurement and modeling for an intra-vehicle environment. The measurement was conducted in time domain beneath a commercial vehicle chassis. Channel data were collected at the same locations for the car in stationary and in moving status. Stochastic tapped delay line model is used to characterize the channels in both cases. Slightly larger number of multi-path components (MPCs) and mean RMS delay are observed in the moving case. Statistical analysis shows that car movement does not significantly affect the characteristics of UWB channel in the intra-vehicle environment.
